Fig. 5 is a flowchart illustrating an information encryption method according to an example embodiment, which may include the following steps, as shown in fig. 5.
In step S110, the terminal acquires the key serial number transmitted by the gateway when generating the control information according to the triggered control operation.
The control information is information for controlling a device related to the local area network.
As shown in the implementation environment diagram of fig. 1, a user operates an APP running in a terminal to generate corresponding control information.
There are various ways for the gateway to transmit the key serial number, and the key serial number may be transmitted to the terminal at a fixed frequency, may be transmitted when the terminal makes an inquiry to the gateway, or may be transmitted by other means.
It should be noted that the key serial numbers sent by the gateway each time are different, even if other terminals attack through spoofing when acquiring a key serial number for a certain time, the gateway generates a decryption key according to the new key serial number after receiving the encrypted information sent by other terminals, so that the encrypted information sent by other terminals cannot be decrypted, thereby further avoiding the attack of other terminals through spoofing, enabling the gateway to successfully decrypt the encrypted information sent by other terminals and mistakenly execute corresponding operations according to the control information obtained after decryption, and ensuring the security of controlling the relevant devices through the local area network.
In step S120, a key is selected from a preset key sequence according to the key sequence number to obtain an encryption key.
The key sequence is preset.
The key sequence comprises a sequential set of a plurality of keys, each key in the key sequence being different from each other.
The key may be a number, a phrase, or other forms, and the specific form of the key is not limited herein. For example, the key sequence is a sequence including 10 ten thousand mutually different numbers.
Therefore, a specific key can be selected from the key sequence according to a specific key sequence number.
The terminal has various ways of selecting the key from the preset key sequence according to the key sequence number, and can select the key sequenced as the key sequence number from the key sequence; or selecting a key before or after the key sequenced as the key serial number from a preset key sequence according to the key serial number; the key may also be selected from the preset key sequence according to the key sequence number in other manners, where a specific manner of selecting the key from the preset key sequence according to the key sequence number is not limited herein.
It should be noted that the key sequences in the terminal and the gateway may be identical or corresponding, that is, after the terminal encrypts information according to the key in the key sequence stored in the terminal, the gateway may successfully decrypt information according to the key in the key sequence stored in the gateway. That is, information encryption and information decryption can be performed by the same one key; the information can be encrypted by one key, and the information can be decrypted by another key corresponding to the encrypted key, so that the gateway can be ensured to be successfully decrypted after receiving the encrypted information.
In step S130, the control information is encrypted by the encryption key to obtain encrypted information.
It should be noted that, the terminal selects a key from a preset key sequence according to a key sequence number to obtain an encryption key for information encryption, and the gateway selects a key from the same key sequence according to the key sequence number to obtain a decryption key for information decryption, and since the key sequences are the same or corresponding, the key sequence numbers are the same, the gateway can successfully decrypt and obtain control information after receiving the encryption information.
In step S140, the encryption information is transmitted to the gateway.
By using the method, when the intelligent home system generates the control information according to the triggered control operation in the control process of the home equipment, the terminal selects the key from the preset key sequence according to the key sequence number sent by the acquisition gateway to obtain the encryption key, encrypts the control information according to the encryption key to obtain the encryption information, and sends the encryption information to the gateway, and because the key sequence number of the encryption key is sent by the gateway, the gateway can obtain the decryption key from the key sequence according to the key sequence number, and further can smoothly identify the control information after receiving the encryption information and decrypting through the decryption key, thereby realizing the encryption and decryption of the control information only through the transmission of the key sequence number, avoiding other terminals from knowing the encryption key of the control information or the decryption key of the encryption information, and when the encrypted information is sent by impersonation, the related household equipment is controlled by mistake, the communication safety in the intelligent household system is ensured, and the safety of controlling the related household equipment is greatly improved.
Optionally, fig. 6 is a detailed description of step S110 in the information encryption method shown in the corresponding embodiment of fig. 5, and as shown in fig. 6, step S110 in the information encryption method may further include the following steps.
In step S111, the terminal receives the key sequence number transmitted by the gateway at a preset time interval.
The time interval for the gateway to send the key sequence number is a preset time range value, the time interval cannot be set too large or too small, and the time interval can be finely adjusted in advance in an actual intelligent home system. In an exemplary embodiment, the time interval is preset to 5 seconds.
When the terminal receives the key serial number sent by the gateway at the fixed frequency, the terminal does not immediately acquire the key serial number and selects a key from a preset key sequence, and only when control information is generated according to triggered control operation, the terminal acquires the received key serial number.
When the terminal generates the control information according to the triggered control operation, the time consumed for encrypting the control information, the time consumed for sending the encrypted information to the gateway and the time consumed for receiving the encrypted information sent by the terminal by the gateway are all very short, so as long as the fixed frequency of sending the key serial number by the gateway is not very high, namely the interval time of sending the key serial number by the gateway is not very short, when the gateway receives the encrypted information sent by the terminal, the gateway can know that the terminal encrypts the key selected according to which key serial number the gateway sends.
In step S112, the key sequence number received at the time of generating the control information is acquired from the key sequence numbers transmitted by the receiving gateway.
By using the method, the gateway sends the key serial number to the terminal according to the preset time interval, so that when the terminal generates the control information, the terminal directly searches the latest received key serial number in the received key serial numbers sent by the gateway, the key serial number does not need to be specially inquired from the gateway, and the convenience of obtaining the key serial number is greatly improved.
Optionally, fig. 7 is another detailed description of step S110 in the information encryption method shown in the corresponding embodiment of fig. 5, and as shown in fig. 7, step S110 in the information encryption method may further include the following steps.
In step S114, the terminal transmits a key serial number acquisition request to the gateway when generating the control information.
In the local area network, the terminal sends a key serial number acquisition request to the gateway through the router.
The key serial number obtaining request is an instruction sent by the terminal to the gateway to request to obtain the key serial number.
In order to ensure that the gateway can successfully decrypt and obtain the control information after receiving the encrypted information, the key sequence number when the terminal selects the encryption key from the preset key sequence is the same as the key sequence number when the gateway selects the decryption key from the preset key sequence. Therefore, when the terminal generates the control information and needs to encrypt the key, the key serial number obtaining request is sent to the gateway to obtain the key serial number sent by the gateway, and then the encryption key is obtained by selecting from the preset key sequence according to the key serial number, so that the key serial number of the encryption key obtained by the terminal is ensured to be the same as the key serial number of the decryption key obtained by the gateway.
In step S115, the key serial number transmitted by the gateway in response to the key serial number acquisition request is received.
By using the method, when the terminal generates the control information, the terminal sends a key serial number acquisition request to the gateway, and requests the gateway to send the key serial number, so that the key serial number of the encryption key selected by the terminal from the preset key sequence is the same as the key serial number of the decryption key selected by the gateway, the gateway is further ensured to be capable of successfully decrypting to acquire the control information after receiving the encryption information sent by the terminal, and the encryption information sent by other terminals through spoofing cannot be successfully decrypted, the communication safety in the intelligent home system is ensured, and the safety of controlling related equipment in the intelligent home system is improved.
Fig. 8 is a flowchart illustrating an information encryption method according to an example embodiment, which may include the following steps, as shown in fig. 8.
In step S210, the gateway receives the encrypted information transmitted by the terminal.
The gateway receives the encrypted information sent by the terminal, and the terminal sends the encrypted information to the gateway through the local area network.
In step S220, in response to receiving the encrypted message, the gateway selects a key from a preset key sequence according to the key sequence number sent to the terminal, so as to obtain a decryption key.
When receiving the encrypted information sent by the terminal, the gateway immediately selects a key from a preset key sequence according to the key serial number sent to the terminal to obtain a decryption key.
Because the key serial numbers are the same and the preset key sequences are the same or corresponding, the gateway can successfully decrypt and obtain the identifiable control information after receiving the encrypted information.
In step S230, the control information is obtained by decrypting the encrypted information with the decryption key.
As mentioned above, the terminal encrypts the control information to obtain encrypted information. Therefore, the control information is obtained by decrypting the encrypted information with the decryption key.
If the encryption key for encrypting the control information by the gateway is the same as the decryption key for decrypting the encrypted information by the gateway, the control information obtained after decrypting the encrypted information by the decryption key can be identified, namely the encrypted information is effectively sent, and the gateway controls the related equipment according to the control information; if the encryption key for encrypting the control information by the gateway is different from the decryption key for decrypting the encrypted information by the gateway, the control information obtained by decrypting the encrypted information by the decryption key cannot be successfully identified, that is, the transmitted encrypted information is invalid. Therefore, when the gateway cannot identify the control information, the gateway indicates that the sent encryption information is invalid, and the gateway discards the control information and does not perform corresponding operation according to the control information.
In step S240, the control information is sent to the relevant home devices, so that the home devices operate according to the control information.
By using the method, when the gateway receives the encrypted information, the gateway selects the key from the preset key sequence according to the key serial number sent to the terminal to obtain the decryption key, and decrypts the encrypted information through the decryption key to obtain the control information.
Optionally, fig. 9 is a detailed description of step S240 in the information encryption method shown in the corresponding embodiment of fig. 8, and as shown in fig. 9, step S240 in the information encryption method may further include the following steps.
In step S241, when the control information is recognized, the relevant device is controlled in accordance with the control information.
In step S242, if the control information cannot be identified, the control information is discarded.
It will be appreciated that if the control information is obtained by successfully decrypting the encrypted information, the content of the control information can generally be successfully identified.
However, in order to avoid that the control information is sent to the related home devices without being able to identify the information content of the control information after the encrypted information is successfully decrypted, the operation of the home devices may be failed, and the home devices may be damaged.
Therefore, after the information content of the control information is successfully identified, the control information is sent to the relevant household equipment, and the safety of controlling the relevant household equipment is greatly improved.
And after the information content of the control information cannot be successfully identified, discarding the control information and not sending the control information to the related household equipment.
Fig. 10 is a schematic diagram illustrating a method for controlling home devices in an intelligent home system according to an exemplary embodiment.
In step S310, the terminal and the gateway respectively receive the key sequence sent by the cloud through communication connection with the cloud.
It can be understood that the encryption key or decryption key selected by the terminal and the gateway are both pre-stored in their respective storage in the form of a key sequence, and then the terminal selects the encryption key from the key sequence according to the key sequence number sent by the gateway and encrypts the control information by the encryption key, and after receiving the encrypted information, the gateway selects the decryption key from the key sequence to be stored by the key sequence number sent to the terminal by the gateway and decrypts the encrypted information according to the decryption key.
When the terminal and the gateway are in communication connection with the cloud for the first time, the cloud sends the key generation information containing the key generation mode to the terminal and the gateway respectively, and the key sequences received by the terminal and the gateway respectively are completely the same, so that the gateway can decrypt smoothly and identify the decrypted control information after encrypting the control information and sending the control information to the gateway.
In step S320, the terminal acquires the key serial number sent by the gateway when generating the control information according to the triggered control operation.
In step S330, the terminal selects a key from a preset key sequence according to the key sequence number to obtain an encryption key.
In step S340, the terminal encrypts the control information according to the encryption key to obtain encrypted information, and sends the encrypted information to the gateway.
In step S350, the gateway receives the encrypted information sent by the terminal, and selects a key from a preset key sequence according to a key sequence number sent to the terminal, so as to obtain a decryption key.
In step S360, the gateway decrypts the encrypted information by the decryption key to obtain the control information.
In step S370, upon recognizing the control information, the relevant device is controlled in accordance with the control information.
